They don't know about the 'underhanded' things. No I am not taking drugs. I was trying to tell Jess to gtfo and my testosterone hormones kicked in.
They're parents. They can tell if you're hiding something from them.
I know from being an observer all my life, and taking notes of the relationship between parents and their respective children. That ontop of the actions I know of, and how the children are acting.
Seeing how you can barely hold yourself together on the internet, I doubt they're clueless.
It's a good thing I've been good all my life and my parents trust me 
Same. I was too focused on other things.
